Hydraulic Pump PTO Speed Increase Gearbox for Tractors, Power rated to 20kW (27 HP input ) 7100 series.
The 3:1 Ratio takes the 540 RPM tractor output and converts it to 1,620 RPM which is an ideal rotation speed for Hydraulic Gear pumps.

With the correctly sized pump mounted to the gearbox: the following oil flows and pressures can be generated.

• 80 Lt/min at 1,800 psi (125 bar)


• 70 Lt/min at 2,200 psi (150 bar)


• 60 Lt/min at 2,500 psi (175 bar)


• 50 Lt/min at 3,000 psi (200 bar)


• 40 Lt/min at 3,600 psi (250 bar)

If you require a hydraulic attachment to run off your tractor but don't have enough hydraulic flow available, this may be the answer.

Match up a pump with the correct flow rate, add an oil reservoir & you have a hydraulic power source.
In the image below is a power/flow chart to help choose a gear pump. This gearbox is rated for a maximum of 20 kW hydraulic power internal stress will cause the gearbox to fail prematurely.

The gearboxes are used mainly for connecting hydraulic pumps to the power take-offs of agricultural tractors ( Male 6T 1 3/8” shafts).

PTO output, standardised at either 540 or 1,000 rpm, is, in this way, increased to optimum operating speeds for the hydraulic pumps.
At 540 Rpm, the output speed is 1620 RPM

Used to power hydraulic Auger, front-end loaders, mowers, rotary sweepers, post hole hammers and borers, pile drivers etc.

There is a choice of three configurations below. Also a choice of 'Spline' coupler.
These gearboxes only take Group 2 or Group 3 DIN and SAE 2 A and SAE B mount pumps.

Please see the chart, & then our pump listings.

This 7000 series will only produce a maximum of 60 LPM @ 175 Bar / 2600 psi.
For more flow with higher pressure, please see our larger 50HP gearbox.
